Ask HN: What do you think about a 3D printer for your child(ren)?

I'm working on a project that may result in a software package that allows children to digitally create toys, then create them in real life on their own (very simple) 3D printer to play with - and I'd love to get your feedback.

If you could include if you're a parent, as well as the age(s) of your child(ren), that'd be very helpful.

Thanks!
